Digital Mental Health Interventions (DHMIS) for Youth: A Systematic Review of Online Counselling Effectiveness

Digital mental health interventions (DMHIs) are increasingly recognized as viable and scalable solutions to address rising mental health concerns among youth. With adolescents and young adults facing heightened psychological challenges such as anxiety, depression, and emotional deregulation there is an urgent need for accessible, flexible alternatives to traditional face-to-face counselling. This systematic literature review explores the effectiveness of online counselling interventions specifically targeted at youth populations. Guided by the PRISMA protocol, we conducted a comprehensive search of two major academic databases Web of Science (WoS) and Scopus focusing on peer-reviewed articles published between 2023 and 2025. After rigorous screening, a total of 25 primary studies were selected for in-depth review and synthesis. The analysis yielded three overarching themes: (1) Effectiveness of Digital Interventions in Supporting Mental Health, where most studies reported positive psychological outcomes including reductions in depression and anxiety symptoms; (2) Challenges in Implementing Digital Mental Health Interventions, highlighting barriers such as user engagement, cultural adaptability, and professional resistance; and (3) Accessibility and Equity in Digital Mental Health Services, emphasizing disparities in digital access, literacy, and the need for inclusive, culturally sensitive interventions. Despite diverse methodologies and digital formats across the reviewed studies, the findings consistently support the potential of online counselling as a complementary approach to youth mental health care. However, the long-term success of such interventions depends on addressing engagement, equity, and integration into existing healthcare systems. This review underscores the need for continued innovation and policy support to optimize the reach, quality, and sustainability of digital counselling services for young populations.
